mxm1275 Posted November 21, 2015 Report Share Posted November 21, 2015 Hello fellow Boxster owners...I have just replaced the water pump on my 2003/ 2.7 986 and thought I would post my experience to help fellow owners as there seems to be some conflicting advice online.Just some pointers for those considering doing this task.Tools required.10mm spanner (open and closed end)Deep 10mm socketNormal 10mm socketSmall cutters (to cut gasket if not replacing thermostat)Normal lifting gear, axel stands etcSundriesLight emery cloth/ paper to clean surfacesNew coolant. I used red/pink non Porsche concentrate (which supercedes the green and blue type)Advice!Replacement of the water pump do-able by the home mechanic- dont be put offYou'll need jack the car up and support to gain access to the middle of the carYou'll need to remove the inspection panel behind the seats. I'm average build and I didn't remove the seats.Drain all of the coolant you can in to a bucket for disposal (I used a washing up bowl for space saving)Replace the belt if you suspect the one you haveYou'll need to cut the new gasket to remove the thermostat bit (save for sometime later) if not using, use cuttersMake a note of which bolts go where and replace the pumpTop up with new coolant, I used an approximate 50/50 mix ishLocate the bleed valve under the radiator cap plastic panel and lift leverStart engine and bleed by running up to tempIf you get an air lock as I did, you'll need to possibly reset the temp error in thr cars memory before the gauge will work again.Go for a drive, take off the axel stands first.Good luck.

ndjfb00 Posted November 21, 2015 Report Share Posted November 21, 2015 Nice post Matt and im sure this gives a few the confidence to attempt the job, wasnt you quoted nearly £600 all in for this at an Indy? Link to comment Share on other sites More sharing options...
mxm1275 Posted November 21, 2015 Author Report Share Posted November 21, 2015 Certainly saved a few quid... total spend on parts was £220 (pump, gasket and coolant) from Eurocarparts. The pump and gasket was genuine Porsche. Porsche specialist quoted just under £600. Link to comment Share on other sites More sharing options...
Milko Posted June 10, 2019 Report Share Posted June 10, 2019 I've just replaced my water pump on my 986. The biggest faff I had was putting the new pump in place without the gasket dropping off or not lining up. After losing my temper and knuckle skin I had a brainwave (for me it's a brainwave). I cut the heads off two longer M6 bolts to give a long studs. Screw these in two of the top holes on the engine, hang the gasket and then offer up the pump, fix a couple of the normal bolts in to tighten up the pump, replace studs with bolts, happy days. Then think to myself "why didn't I think of that an hour ago? Why didn't I take pictures? I removed the driver seat as I carry a few extra pounds and my body doesn't bend like it used to. Wear a head torch. Link to comment Share on other sites More sharing options...
Nobbie Posted June 10, 2019 Report Share Posted June 10, 2019 To help with getting air out of the system it is useful to leave the back of the car on axle stands with the bleed valve open when you first run it upto temperature with a few revs. Link to comment Share on other sites More sharing options...

Wear a head torch. I have found in the past to help locate and keep in place gaskets and such light items. Just a dab of grease to make it sticky and it generally holds them. Check that grease will not interfere with the parts in question , but in general it doesn't. Link to comment Share on other sites More sharing options...

Some of the bolts are longer than others. I saw a report from another enthusiast admitting that he lost track of the bolts and inserted a long bolt into a short hole. He continued tightening the bolt until the head sheared off. Link to comment Share on other sites More sharing options...
BTM520 Posted September 10, 2019 Report Share Posted September 10, 2019 Any particular coolant that's recommended or should be avoided? Link to comment Share on other sites More sharing options...
